What are the pros and cons of pre-paid debit cards?

What do you know about computer video cards?

• Is there any real advantage in getting dual video cards instead of one good one with the same amount of VRAM? Why do some of the new computers have 2 cards instead of just one? (Example 2 NVIDIA 512 MB cards or just 1 NVIDIA 1024 card?) Tell me any pros or cons that you are aware of concerning this. (Obviously power consumption is one factor.) Will two cards allow faster processing for game playing or is it the same as one big/good card? The best explanation gets the best answer pick. Thanks for your help.

• Answer:

  Dual cards (SLI or Crossfire) produce smoother performance at high resoutions with all the eye-candy turned on. Both cards are used to render the image to a single screen. They are ideal if you play at ultra-high (1600x1200) or widescreen resolutions (1680x1050, 1920x1200). they're overkill for 17" or smaller screens (1280x1024 res or lower). note that some games show no benefit from a dual card setup. And remember that video card RAM (512 vs 1MB) is not as important as the number of pipelines, stream processors as well as core clock and memory clock speeds on the card.
